ATTACHMENT FOR WiNUOflFSASH.

SPECIFICATION forming part of Letters Patent No. 710,811, dated October 7, 1902. Application filed September 28, 190]. Serial No. 76,831. (No model.)

1!) all whom it may concern.-

Be it known that I, LEONARD SEIBERT, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Attachments for lVindow-Sash, of which the following is a specification.

My invention relates to improvements in attachments for window-sash, its object being to provide means for preventing the sashes of the window being opened on the outside beyond a predetermined point.

To this end my invention consists in the features of construction and combination hereinafter specifically described and claimed.

In the accompanying drawings, forming part of this specification, Figure 1' is a vertical cross-section of the parts of the upper and lower sash of a window fitted with my improved attachments. Fig. 2 is a top view of the same. Fig. 3 is a vertical cross-see tion of the upper and lower sash, showing my invention arranged in connection with the ordinary sash-fastener; and Fig. 4. is a top view of the same.

In the drawings, A represents the upper and B the lower sash of the Window. To the lower horizontal rail 2 of the upper sash, inside the pane 3, is secured a socket-piece 4, into which fits the lower end of the rod 5, the upper end 6 of said rod being inwardly bent. A thumb-screw 7 projects through the side of the socket-piece 4 and into the rod, as shown in Fig. 1.

In use the device is set, as shown in Fig. 1, and the sash opened until the upper rail 80f the lower sash abuts against the inturned end 0 of the rod 5. The space between the lower rail of the upper sash and the pane of the lower sash is not sufficient to render the thumb-screw 7 accessible, so that the device cannot be tampered with without'breaking the glass. When the window is closed, the socket-piece at will stand above the upper rail 8 of the lower sash, leaving the thumb-screw 7 accessible. The thumbscrew can then be turned out of the opening in the rod 5 to allow the removal of said rod.

In Figs. 3 and 4 is shown a modified construction of my device. In this form the locking member 9 of the regular sash-lock is formed with a socket portion 10 to receive the rod 5. The rod 5 is secured in the socket portion 10 in the same manner as in the construction shown in Fig. 1. IVhen the locking member 9 of the sash-lock is turned to unlocked position, as shown in Fig. 4, the rod will be turned into position to engage with the upper rail of the lower sash when the window is opened. WVhen the window is opened, as shown in Fig. 3, any turning of the rod will bring the end of the member 9 against either the pane of the lower or of the upper sash. The turning of the rod 5 is thus absolutely prevented unless the window is closed.

By the use of my invention the window can be left partly open without any danger of unwarranted opening from the outside.

I claim 1. The combination with the upper and lower sash of a window-frame, of a socketplate supported upon the lower rail of the upper sash, a rod fitted in said socket-plate, said rod having an inwardly-projecting upper end, and means for detachably securing said rod in said socket-plate.

2. The combination with the upper and lower sashes of a window-frame, of a socketplate supported upon the lower rail of the upper sash, a rod fitted in said socket-plate, said rod having an inwardly-projecting upper end, and a screw detachably securing said rod in said socket-plate, substantially as set forth and described.

In testimony whereof I aflix my signature in presence of two witnesses.

LEONARD SEIBERT. lVitnesses:
